What to know about Magnetic field helps binary star systems form, new simulations indicate

New supercomputer simulations indicate that interstellar magnetic fields help binary protostars move closer together by removing angular momentum. The research, published in the Monthly Notices of the Royal Astronomical Society, suggests this process may also apply to the evolution and merger of supermassive black holes.

Why it matters

These results can help explain the characteristics of the binary star systems observed in the Milky Way.

Common ground

The results can also be extrapolated to binary black holes, giving insights into how supermassive black holes evolve.

Perspective signals
